someone have the same proble than me? i cant make the condition : "_destination != null" it says that MArker cant be nulleable and always will be true. help please! nice tutorial
Hey I have tried the same code from the video but the Polylines don't work I don't know why I've also tried taking the code from your repo also switched my api key with yours but still the poly lines don't show up I can't understand why can you please help me?
Hello, Can you help me? is giving this error. Because MAPGO depends on google_maps_flutter >=2.0.0-nullsafety which requires SDK version >=2.12.0-0 =2.0.0-nullsafety which requires SDK version >=2.12.0-0
This package doesn't use the google maps API it's using the google Android SDK and google IOS SDK. The reason I'm calling out this difference is because maps api is unlimited, android sdk and ios sdk have limits to how many requests (currently $200 worth per month at the time I'm writing this) that you can have on your key.
Nice video, learnt a lot from your channel. Can you please make a tutorial on how to write and read video files with firebase, since there not enough tutorials online to learn to handle videos? And videos are an essential feature of most apps.
I am having issues because GoogleMapController and Marker objects cannot be null. I was able to get around this issue for the GoogleMapController by adding the late tag in front of the declaration, but I cannot find a workaround for checking if the Markers are null. I get a warning that says they cannot be null so the comparison is always true when checking if != null. Anyone know a fix?
I fixed this by initializing the Markers to have position = LatLng(0.0,0.0) which is very far outside of the intended use area of the app I am building, and compare Marker.position to LatLng(0.0,0.0) instead of checking if Marker == null
Yes I got the same error. this is flutter null safety error. Try using // @dart=2.9 at the start of your main.dart file. it will solve null safety error.
bro its really good video but i have some problems in my code, whenever i try to initialize MARKER it give me an error because of null safety, but it is not giving this error to you.

Hi, thanks for this great tutorial. Is it possible to place the map in, for example, a container that uses just 1/3 of the screen? That way I could use the rest of the screen to place some other information :)
Facing same problem. I suggest use MapBox direction api, to draw a route we need the set of points to draw route, MapBox give us for free, also give duration and distance. Google maps direction api JSON returned is different from MapBox direction api but they have commun things.
@@AnkitMishra-th6gb Hello are refering to directions api bc theres no route api in cloud console. Please can assist me im also not to draw the polyline eventhough i get and decode the polyline string. Also i have a billing account and directions api enabled
my app only shows the total distance, duration, and polyline on the initial build. When I set a new origin and destination, it can't set the destination, which the DirectionsRepository.getDirection ==> reponse.statuscode failed. It only works when I wipe data or rebuild the virtual device again. It may be a memory leak. Wonder you might have the solution to this problem. Overall, I highly appreciate your work and thanks for providing such quality work.
thanks for this great tutorial however it is a shame that we still can not use widgets, the integral part of Flutter, as markers and we are limited to some rasterized images as markers. I will not use Google Maps until they support this. I don't want my app's map to look like it is from 2012:/
